Product: HP Probook 470 G3
Operating System: Microsoft Windows 10 (64-bit)
Hello,
my Probook has the following error led code, but i couldn't find something about this code on the internet:
When connecting to power (power supply or battery), the following LEDs flashes together only once for 3 seconds:
- Power-LED
- Num-LED
- Capslock-LED
After that, nothing happens, screen is black. Has anyone help, to find, what this error code means?
Thank you all!
Regards, Bryan.
